` To @ZZ to from t may concern Be it lknown thatnllfiinnr l". blomus, acitizen oi' the United States, residing at Collingswood, in the countyof Camden and State of New, Jersey, has invented certain new and usefullmprovements in Furnace 'frates, oi which lication. y

'.i'fhis invention relates to improvements in forced and natural dralftwater gratos.

The `principal object ot the invention is to provide moans to obtain ahorizontal dralt iu a grate cit the elv `described whereby the linerrudes ot iuel will not be disturbed, as in A provided with u directupward draft, and the same is an improvement on Letters Patent No.1.261,268

issued to myself and Bitner Shinn, April y 2, i918; lLetters Patent No.1,348,235 granted to myself under detect August 3, 1920 and anapplication ytor Letters Patent :tiled by me March 1921, bearing SerialNumber 449,524;

A further object of. the invention is to simplify the meansot passingair through the vgrate and to` control `the quantity of such air, in`order-to obtain the proper combustion oi:l the VJfuel on saidgrate underany und all conditions. i f

'A further object ofthe invention is to provide communicating meansbetween the cored openings inv the grate `and the surface ot' .nidgrate, whereby the volume ot' air to be distributed'orer thegrate'surfaoe may be exactly regulated. f

ln carry' g out the above stated, an other, objet-ts I providea deviceof new and `novel construction whereby the ascending draft oi1 air thruthe cored vertical openings in said grate is deflected and distributedyhorizontally over the surface of the grate, the air openings thru whichthe air is distributed being so` constructed `and arranged that the airloses its torce or v.f'ioleuoe before the distribution thereof takesplace and the unionot the air forces at the point where the air leavesthe discsis prevented,obviat ing a multiplicity ot' openings with anupn'ard draft which cause a lifting and disturbance oit` the fuel,detrimental to the burning thereof where coa-l dirt andthe finer gradesol fuel are used and causes the tubes, combustion chamber and chimney toill with unoonsumed particles of said fuel. This result l" iind in ipractice is` absolutely 'prevented by the use of my indirect horithefollowing is a vs )eci- 1921. serial No. 461,491.

Referring tothe Adrawings in detail the.` numeral l0 designates a liregrate `provided at the :front with aqwater inlet pipe ll whereby water12 enters and circulates thru said grate l0.

A. water outletpipe 13 provided at the back of said grate'lO Whereby.the water after circulating` through said grate and being subjected tothe heat therein is carriedoff, thus providing for a continuouscirculation of the water through said grate` preventing the overheatingandk melting` thereof.

T he water 4flow and return pipes ll and t3, respectively, are connectedwith the boiler,

water tank or other source ot `supply. y

An air chamber '14: is provided having the door l5 tor access thereto`and a latohl to 'secure the same'iin a closed position.

'This door ihowever., ma be secured by means ot' a bolt or othersuitable means asy will insure, as near as connection.

possible, an air tight To obtain forced draft air is forced` by a bloweror other suitable means, through the pipe l into and thru the airchamber.lal

discs vtical cored opening-s or holes 18, aforesaid,y

and the top o' said grate 1,0 is provided with the sunken grooves orchannels 22. rlhe sunken grooves 22, substantially oblong in orin,radiate horizontally `from the cored openings 18 in said grate l0. lnsaid cored openings 18, through Which air is admitted to the grate l0,from the air chamber il, metal discs 19 are positioned, said discs i9being tapering orconical in form, as particularly illustrated in Fig.oit' the drawings, to fit Within said `openings 18, and provided withheads 2l, sealing the dire-rt or vertical. outletsfof the openings 18.

'The said discs 19 are provided with flanged heads 2l and beneath saidheads are provided with vertical tapering grooves 2O adapted tocommunicate with the grooves 22 inthe upper surface of the grate 'l0radiating from the cored openings i8, whereby said heads 2l act asdeflectors el the air travellingup the openings 18 from the air chamberlll, thereby vcausing said air to travel through the vertical grooves52,0 and then horizontally through the grooves 22 along the uppersurface or'. the grate l0, in-

stead of directly upwardly and vertically as inl theinventionhereinbeicore cited; the heads 21 closing vthe vertical outlets of theopenings '18. l

l have illustrated in the drawings tive vertical grooves and livehorizontal grooves 22. These various gii'ooves may be or' such numberfas.may be found requisiteilor the purposes herein stated. v

lt Will benoted that the grooves 22 are "for air travel under the lirebed and are so positioned that the air travelling throughone groove'does not communicate directly or gain admission to any o'tiier grooveradiating :from the same orv other cored opening 18.

The discs 19 by a slight rotary movement thereof will regulate theamount of vair to be -nieate therewith.

admitted to the grooves Edin the grate lll 4trein the openings 18;permitting the 'full volume of the vair ascending through said ope1'nns18 to pass to the grooves 20 1t the groove-s 22in the said discsV 'i9fully coinmurl`his meansv ot' control of the volume ot air to beadmitted to the grate by the communicating grooves 20 and 22 isparticularly illustrated in Fig. 3 of the drawings.

Although in the drawings l have shown certain details of constructionand in the preceding, have described such details, it is obvious that lneed not be limited thereto other-Wise than to the extent to which theappended claims restrict me.

llavingthus described. my inventionwhat l claim as new and desire tosecure by Letters Patent is f l. ln a grate ot the class described,vertical channels therethrough, discs positioned inthek outlets of saidchannels pro-vided with langed heads adapted to close said outlets,horizontally extending grooves in the upper sunliace-oi'f said grateadapted for communication* with said channels `and vertical grooves insaid discs adapted to establish communication between said channels andsaid horizontal grooves.; saidydiscs being rotatable to open land closesuch communication substantially as described.

2. ln a grate of the class described, vertical channelstherethrough,discs positioned in the outlets otsaid channelsprovided with flangedheads, adapted to close said outlets, horizontally extending grooves inthe upper surface vof said grate adapted `for communication` with saidchannels and, vertical grooves in said discs adapted to establishcommunication between said 1 channels and said horizontal grooves; saiddisc being partially rotatable to regulate the degree of such comniunication, scribed.

In testimony whereof lafhx my signature.
